Design Challenges of the Thematic Mapper

Tuple-Space Mapper: Design, Challenges and Goals

Library-based and pre-compiled visualization tools incur many penalties that hinder the adoption of visualization as a technique for many applications. Libraries necessitate familiarity with the data structures and control flows that are incumbent in traditional programming, but not central to visualization. Task-specific visualization applications alleviate these needs, but induce users to mov...

the role of thematic structure in comprehending spoken language

in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...

Waveband Evaluation of Proposed Thematic Mapper in Forest Cover Classification

This study involved the evaluation of the characteristics of multispectral scanner data relative to forest cover type mapping, using NASA's NS-OOI multispectral scanner to simulate the proposed Thematic Mapper (1M). The objectives were to determine: (1) the optimum number of wavebands to utilize in computer classifications of TM data; (2) which channel combinations provide the highest expected ...

Landsat D Thematic Mapper Image Resampling for Scan Geometry Correction

Feature Selection Methodologies Using Simulated Thematic Mapper Data

This study* investigated computer classification performances for forest and other cover types using Thematic Mapper Simulator (TMS) data collected by NASA's NSOOI scanner. Specifically, results based on the use of a common feature selection measure -transformed divergence (TD) were compared to those based on a principal component transformation for the purpose of evaluating the capabilities of...
